Understanding Basic Arithmetic Operations
Let’s break down each operation and its formula.
1. Addition (+)
Addition combines two numbers to produce a sum.
Formula:
Result = A + B
Example:
5 + 3 = 8
2. Subtraction (-)
Subtraction finds the difference between two numbers.
Formula:
Result = A − B
Example:
10 − 4 = 6
3. Multiplication (*)
Multiplication calculates the product of two numbers.
Formula:
Result = A × B
Example:
6 × 7 = 42
4. Division (/)
Division splits one number by another.
Formula:
Result = A ÷ B
Example:
20 ÷ 5 = 4
⚠️ Important: Division by zero is not allowed and will result in an error.
